Chapter 30: Respiratory Flashcards
Alveoli
Empty sacs that fill with air where oxygen diffusion occurs
Upper respiratory use
Filer the tract, warms and humidifies
Surfactant
Lubrication to prevent friction
Pleural effusion
Water in cavity
Pleural cavity use
Protector of lung
Best position during respiration
Sitting
Atelectasis
Stiff lung
Medication that caused coughing
Ace inhibitors
Dispnea
Shortness of breath
Level 3 despeña
Talking and performing ADL (activities of daily living)
Orthopnea
Positional dyspnea
Clubbing
Shows hypoxia
Bronchial sounds
Over trachea, loud, harsh, high pitch
Inspiration shorter than expiration
Vesicular sounds
Soft, breezy, lower pitched inspiration is longer/greater than expiration
Bronchovesicular sounds
Between both bronchial and vesticular sounds, equal in inspiration and expiration
Broncoscopy
Visually see what’s happening in chest (of airways)
Stack cough
Type of coughing after surgery (never deep cough)
Venturi mask
Precise amount of oxygen
Wheezing/bronchi
Course wheeze
Crackles/rales
High pitched heard at end of inspiration
Pleural friction rub
Dry running or grating sound
Nasal cánula
Most common and conviene
22-44%
Simple oxygen mask
Most common midrange O2
40-60%
Reservoir type
Used for critically ill
Up to 90%
Nonrebreather
Highest load of oxygen administered
Pulse oximetry readings reflect what?
Number of available oxygen receptors on hemoglobin molecules
PaCO2 normal range
35-45 mmHg
Flow meter
Gauge used to regulate the amount of oxygen that a client receives
Manifestations of hypoxia
Tachycardia: Increase respiration
Tachycardia: increase heart rate
Elevated BP
Cool skin
What helps postural drainage?
Chest percussion and vibration
